What work is done on the crate by the weight of the crate

Reference no: EM13531336

To push a 62.0-kg crate up a frictionless incline angled at 27.0° to the horizontal, a worker exerts a force of 408 N parallel to the incline. The crate moves a distance of 4.30 m. What work is done on the crate by the weight of the crate? What work is done by the normal force exerted by the floor on the crate? What is the total work done on the crate?
